Usage : ${__ScriptName} [options] <install-type> [install-type-args]
Installation types:
- stable Install latest stable release. This is the default
install type
- stable [branch] Install latest version on a branch. Only supported
for packages available at repo.saltproject.io
- stable [version] Install a specific version. Only supported for
packages available at repo.saltproject.io
To pin a 3xxx minor version, specify it as 3xxx.0
- testing RHEL-family specific: configure EPEL testing repo
- git Install from the head of the master branch
- git [ref] Install from any git ref (such as a branch, tag, or
commit)
- onedir Install latest onedir release.
- onedir [version] Install a specific version. Only supported for
onedir packages available at repo.saltproject.io
- onedir_rc Install latest onedir RC release.
- onedir_rc [version] Install a specific version. Only supported for
onedir RC packages available at repo.saltproject.io
- old-stable Install latest old stable release.
- old-stable [branch] Install latest version on a branch. Only supported
for packages available at repo.saltproject.io
- old-stable [version] Install a specific version. Only supported for
packages available at repo.saltproject.io
To pin a 3xxx minor version, specify it as 3xxx.0
Examples:
- ${__ScriptName}
- ${__ScriptName} stable
- ${__ScriptName} stable 3006
- ${__ScriptName} stable 3006.1
- ${__ScriptName} testing
- ${__ScriptName} git
- ${__ScriptName} git 2017.7
- ${__ScriptName} git v2017.7.2
- ${__ScriptName} git 06f249901a2e2f1ed310d58ea3921a129f214358
- ${__ScriptName} onedir
- ${__ScriptName} onedir 3006
- ${__ScriptName} onedir_rc
- ${__ScriptName} onedir_rc 3006
- ${__ScriptName} old-stable
- ${__ScriptName} old-stable 3005
- ${__ScriptName} old-stable 3005.1
Options:
-a Pip install all Python pkg dependencies for Salt. Requires -V to install
all pip pkgs into the virtualenv.
(Only available for Ubuntu based distributions)
-A Pass the salt-master DNS name or IP. This will be stored under
\${BS_SALT_ETC_DIR}/minion.d/99-master-address.conf
-b Assume that dependencies are already installed and software sources are
set up. If git is selected, git tree is still checked out as dependency
step.
-c Temporary configuration directory
-C Only run the configuration function. Implies -F (forced overwrite).
To overwrite Master or Syndic configs, -M or -S, respectively, must
also be specified. Salt installation will be ommitted, but some of the
dependencies could be installed to write configuration with -j or -J.
-d Disables checking if Salt services are enabled to start on system boot.
You can also do this by touching /tmp/disable_salt_checks on the target
host. Default: \${BS_FALSE}
-D Show debug output
-f Force shallow cloning for git installations.
This may result in an "n/a" in the version number.
-F Allow copied files to overwrite existing (config, init.d, etc)
-g Salt Git repository URL. Default: ${_SALTSTACK_REPO_URL}
-h Display this message
-H Use the specified HTTP proxy for all download URLs (including https://).
For example: http://myproxy.example.com:3128
-i Pass the salt-minion id. This will be stored under
\${BS_SALT_ETC_DIR}/minion_id
-I If set, allow insecure connections while downloading any files. For
example, pass '--no-check-certificate' to 'wget' or '--insecure' to
'curl'. On Debian and Ubuntu, using this option with -U allows obtaining
GnuPG archive keys insecurely if distro has changed release signatures.
-j Replace the Minion config file with data passed in as a JSON string. If
a Minion config file is found, a reasonable effort will be made to save
the file with a ".bak" extension. If used in conjunction with -C or -F,
no ".bak" file will be created as either of those options will force
a complete overwrite of the file.
-J Replace the Master config file with data passed in as a JSON string. If
a Master config file is found, a reasonable effort will be made to save
the file with a ".bak" extension. If used in conjunction with -C or -F,
no ".bak" file will be created as either of those options will force
a complete overwrite of the file.
-k Temporary directory holding the minion keys which will pre-seed
the master.
-K If set, keep the temporary files in the temporary directories specified
with -c and -k
-l Disable ssl checks. When passed, switches "https" calls to "http" where
possible.
-L Also install salt-cloud and required python-libcloud package
-M Also install salt-master
-n No colours
-N Do not install salt-minion
-p Extra-package to install while installing Salt dependencies. One package
per -p flag. You are responsible for providing the proper package name.
-P Allow pip based installations. On some distributions the required salt
packages or its dependencies are not available as a package for that
distribution. Using this flag allows the script to use pip as a last
resort method. NOTE: This only works for functions which actually
implement pip based installations.
-q Quiet salt installation from git (setup.py install -q)
-Q Quickstart, install the Salt master and the Salt minion.
And automatically accept the minion key.
-R Specify a custom repository URL. Assumes the custom repository URL
points to a repository that mirrors Salt packages located at
repo.saltproject.io. The option passed with -R replaces the
"repo.saltproject.io". If -R is passed, -r is also set. Currently only
works on CentOS/RHEL and Debian based distributions and macOS.
-s Sleep time used when waiting for daemons to start, restart and when
checking for the services running. Default: ${__DEFAULT_SLEEP}
-S Also install salt-syndic
-r Disable all repository configuration performed by this script. This
option assumes all necessary repository configuration is already present
on the system.
-U If set, fully upgrade the system prior to bootstrapping Salt
-v Display script version
-V Install Salt into virtualenv
(only available for Ubuntu based distributions)
-x Changes the Python version used to install Salt.
For CentOS 6 git installations python2.7 is supported.
Fedora git installation, CentOS 7, Ubuntu 18.04 support python3.
-X Do not start daemons after installation
-y Installs a different python version on host. Currently this has only been
tested with CentOS 6 and is considered experimental. This will install the
ius repo on the box if disable repo is false. This must be used in conjunction
with -x <pythonversion>. For example:
sh bootstrap.sh -P -y -x python2.7 git v2017.7.2
The above will install python27 and install the git version of salt using the
python2.7 executable. This only works for git and pip installations.
